Nothing original. These wave energy startups come and go. There are at least half dosen anchor floating energy harvesters demoing and failing. Even the location are similar. Demo in North Ireland or Northern Spain where conditions are optimal, operate few years. This is from 2021 from already bankrupt startup that has platforms across the world. https://www.oceanenergy-europe.eu/industry-news/wellos-wave-energy-device-starts-generating-power/ https://www.oceanenergy-europe.eu/industry-news/wellos-wave-... The concept is not competitive with wind and solar. Peak power is 600kW is small, you can't scale the concept to 10WM where it would become cost effective. Profits comes from mild weather conditions. During peak power generation the price of electricity goes towards zero or negative. The maintenance and investment costs kill profitability.

The ability to tune and detune to the ocean conditions is unique. It addresses the two key challenges that have held back wave energy, storm survival and efficient generation in regular sea condition.

  But is it meaningfully unique? Comparisons against other failed wave energy projects do not seem meaningful. Show us comparison relative to wind power in the same area in Cost per megawatt and average power generation conditions. The marketing always forgets to compare against real competition.

It is highly scalable. https://youtu.be/-XWbVMtNnaw?si=AU-mA-v5Ze7v36Zw https://youtu.be/-XWbVMtNnaw?si=AU-mA-v5Ze7v36Zw With a modular approach, adding thousands of them in clusters. Modularity, with many small identical units has the best track record for competitive megaprojects. Think solar PV panels or battery cells as the equivalent ’lego piece’ to a CorPower bouy in a CorPack cluster. https://sites.prh.com/how-big-things-get-done-book https://sites.prh.com/how-big-things-get-done-book

  (building more units is trivial scaling). What I mean is that there is no return to scale benefits per unit that would bring down the cost per unit. Wave size and wavelength puts limit to energy that can be extracted from single unit. Material costs, including the copper for power lines _per_unit_ determine the price. Unless you can ramp up the energy per unit massively, the concept is not competitive with wind power. Wind turbines at sea can do 10-15 MW per unit today and 22MW turbines are coming. If you want to prove me wrong, show us cost per megawatt calculations. For wind turbines the cost is roughly US$1.3 million per megawatt (MW) and maintenance is 1-2 cents per kilowatt-hour produced.
